BARDA`s Role in Combating Antibiotic Resistance
BARDA’S ROLE IN COMBATING ANTIMICROBIAL RESISTANCE Joe Larsen, Ph.D. Deputy Director BARDA Division of CBRN Medical Countermeasures March 2016 Resilient People. Healthy Communities. A Nation Prepared. BARDA’s Mission Support advanced development of and make available medical countermeasures for CBRN threats, pandemic influenza, and emerging infectious diseases by transitioning MCM candidates from early development across the “Valley of Death“ into advanced development to regulatory approval O’Neill Building, Washington, DC MCM Development Pipeline Core Service Assistance & Response Infrastructure MCM Stockpiling Support the advanced development of medical countermeasures for CBRN, pandemic influenza, and emerging infectious disease threats Manufacturing Infrastructure FDA Approvals BARDA Partnerships Highly Dedicated and Talented Team 3 Development is Expensive, Lengthy and Risky IND PHASES Discovery Preclinical Development NDA/BLA Phase I Phase II Phase III NIH DoD NIH&($11.8B) Licensure Production & Delivery PBS $4.3B* ($5.6B) Project BioShield BARDA ARD ($540M) $3.1B* BARDA PRODUCT PIPELINE Valley of Death Licensed Product Ebola MCMs 2014-2015 MERS-COV MCMs 2012-2015 1-3% 5-17% 10-25% 18-35% 45-70% 90% PROBABILITY OF SUCCESS TO LICENSURE TIME PIPELINE PHASE COST 3-7 yr $100M -130M 0.5-2 yr $60-70M 1-2 yr $70M-100M 2-3.5 yr $130M-160M 2.5 -4 yr 1-2 yrs $190M-220M $18M-20M *Represents $1.8B transferred from PBS to support ARD FY09-13, $415M FY14, FY15 * $1.8B transferred to ARD, $255M FY14, FY15 4 Products Stockpiled under Project BioShield Smallpox Radiation Anthrax Chemical Botulism 5 Products Stockpiled under Project BioShield – New in FY 2015 Burn MCMs Silver Impregnated Bandages Enzymatic Debridement Cell-based Skin Substitutes 6 Autograft-Sparing Technologies BARDA Supported FDA Approved Products Cell-based Influenza Vaccine Recombinant-based Influenza Vaccine Novartis Protein Sciences Corp.

The Antibiotic Development Gap No New Classes to Treat Gram Negative Bacilli For 4 Decades 9 The Pipeline is Insufficient 504 candidates in Phase 2/3 clinical development for oncology as of May 2015 28 antibiotics in Phase 2/3 clinical development as of March 2015 7 have predicted efficacy against resistant Gram negative ESKAPE pathogens 14 have predicted efficacy against CDC Urgent Threat pathogen Pew Charitable Trust March 2015 HemOnc today May 2015 10 Industry Engagement in New Antibiotic Development # of companies Over the past 15 years (1998-2013) • 14 entries • 36 exits • New companies emerging in 2015, but we have a lot of ground to reclaim Adapted from Rex, JH Graphic adapted from Kinch MS et al. Drug Discovery Today, July 2014. Corporate Entries Corporate Exits 11 The Last Line has Been Breached “The emergence of MCR-1 heralds the breach of the last group of antibiotics, polymyxins, by plasmid mediated resistance.” “Although currently confined to China, MCR-1 is likely to emulate other global resistance mechanisms, like NDM-1” 12 Through the Looking Glass by Lewis Carroll “Well, in our country," said Alice, still panting a little, "you'd generally get to somewhere else—if you run very fast for a long time, as we've been doing." "A slow sort of country!" said the Queen. "Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!" 13 The BARDA Model The BARDA model works to address market failures 24 Products FDA approved/cleared for biothreats and pandemic influenza 15 Products stockpiled for emergency use This model is being successfully applied to antimicrobial resistance Utilization of novel public:private partnerships to incentivize antibiotic research and development 4 products in Phase III clinical development 14 BARDA Antibacterial Funding Priorities Drug Class • Unprecendented • Novel Target • Novel Chemistry • Precedented • Reduced AR • Nontraditional Therapies • mAbs, phage • Infection prevention/interdic tion • Vaccines • Microbiome Antibiotic Resistance • C. difficile • CRE • N. gonorrhea • Acinetobacter • ESBLs • VRE • Pseudomonas • MRSA • Strep pneumo • VRSA • Streptococcus Biothreat • B. pseudomallei • B. mallei • F. tularensis • Y. pestis • B. anthracis BARDA’s Antimicrobial Portfolio 16 BARDA’s Portfolio Partnership for Antibacterial Drug Development Established 5 year $200M public:private partnership in May 2013 Utilizes HHS’s first use of Other Transactional Authority Supports the development of multiple antibiotic candidates Allows for activities and resources to be adjusted fluidly to adapt to technical risk and programmatic priorities Governance is through a BARDA:GSK Joint Oversight Committee 17 Combating Antibiotic Resistant Bacteria (CARB) In February 2014 OSTP/NSC initiated the President’s Initiative on Combating Antibiotic Resistant Bacteria BARDA was asked to lead the government working group that developed the National Strategy for Research and Development of new antimicrobial therapies 18 National Strategy GOAL 4: Accelerate Basic and Applied Research and Development for New Antibiotics, Other Therapeutics, and Vaccines Action Plan Metrics Within one year: Status BARDA will create at least one additional portfolio partnership with a pharmaceutical or biotechnology company to accelerate development of antibacterial drugs. BARDA and NIH will work to develop a strategy for establishing the Antibiotic Resistance Biopharmaceutical Incubator (ARBI). Economic WG will provide an analysis of economic incentives and provide recommendations for implementation 20 Program Initiated Projected Program Initiation FY16 Recommendations provided to OSTP in March 2015 Key Features of the AZ Partnership • HHS’s 2nd ever use of Other Transaction Authority • Partnership will support a portfolio of antibacterial candidates, the lead of which is aztreonam-avibactam (ATMAVI) • Strategic decisions will be made by a BARDA-AZ Joint Oversight Committee • Fulfills requirement in CARB National Plan that ASPR/BARDA create at least one additional portfolio partnership with a pharmaceutical or biotechnology company by March 2016 to accelerate development of new antibacterial drugs • Establishes international collaboration between BARDA and the EU’s Innovative Medicines Initiative (IMI) • Both entities will provide support for ATM-AVI pivotal trials 21 Incubator • A robust early stage R&D pipeline of antimicrobial products is needed to counter the increasing threat of antimicrobial resistant infections • There is a need to create an environment to rapidly develop and commercialize new antimicrobial products • NIAID and BARDA will collaborate to establish a new program using a Cooperative Agreement to fund a Biopharmaceutical Incubator(s) to identify, assemble, and accelerate a portfolio of innovative early antibacterial products • BARDA/NIAID have been conducting market research and have identified models that currently exist to support the Incubator concept 22 Incubator/Accelerator Start UP Academ ic Lab Start UP NIH $ BARDA Third Party Start UP BARDA will provide funding to a third party. Together, NIH and BARDA will set strategic goals for the third party and monitor progress in meeting those goals. Midsize d Compa ny Academ ic Lab Third party could be a nonprofit, Evergreen fund, existing incubator, etc. Discovery/Hit to Lead Phase 1 X Antibiotic Candidate Antibiotic Candidate X Antibiotic Candidate X Antibiotic Candidate Antibiotic Candidate X Antibiotic Candidate X Funding will be used to conduct R&D studies that will advance a candidate drug in development. Procurement Sensitive: Not for Distribution CARB Accelerator Funding Opportunity Announcement was released on February 17, 2016 Link to funding announcement: EP-IDS-16-001 Pre-application workshop is March 3rd at HHH Building Letters of intent are due: March 10th Technical Assistance Call: March 18th BARDA is anticipating a $30M initial investment and is projecting up to $250M over the life of the agreement, pending availability of funds BARDA is looking for innovative means to leverage the Federal investment to increase the impact of the Accelerator 24 Economic Incentives 25 BARDA’s Antimicrobial Program Summary: BARDA’s antimicrobial program will continue to support the development of novel antimicrobials and diagnostics to address the growing public health threat of antimicrobial resistance and biothreat pathogens BARDA will expand our portfolio of partnerships in FY16 BARDA is actively conducting outreach to relevant stakeholders to communicate our plans to implement the CARB National Strategy 26 Thank you! • www.fedbizopps.gov ─ Official announcements and detailed information about all government contract solicitations.
